Unexplained loss of muscle mass, also known as atrophy, can be caused by a variety of factors. Some of the most common reasons include:
- Aging - As we get older, we naturally lose muscle mass due to declines in hormones like testosterone and growth hormone. This can begin as early as age 30.
- Inactivity - If you stop using your muscles through lack of exercise or spending prolonged time bedridden, the muscles will begin to shrink from disuse. This is sometimes referred to as disuse atrophy.
- Poor nutrition - Eating an imbalanced diet that lacks protein and calories can cause the body to break down muscle tissue for energy. This is known as starvation atrophy.
- Chronic diseases - Conditions like cancer, kidney failure, COPD, and congestive heart failure are linked to cachexia, which is the extensive loss and weakening of muscle.
- Nerve damage - Injuries or diseases that affect the nerves can interrupt signals between the nerves and muscles causing rapid wasting. This is known as neurogenic atrophy.
- Medications - Certain drugs like corticosteroids can trigger the loss of muscle mass as a side effect. Always consult your doctor.
- Muscle diseases - Disorders that directly damage or inflame the muscles themselves like muscular dystrophy and polymyositis can result in progressive atrophy.
If you are experiencing
unexplained muscle wasting, it is important to see your doctor for an evaluation. They will do a full physical exam and take a medical history. They may check lab tests like urine and blood counts, vitamin D, testosterone, and thyroid levels.
Further testing like
X-rays, MRIs, EMG, and muscle biopsies can help pinpoint potential causes. Be prepared to discuss your diet, activity levels, medications, family history, and any other symptoms you may have.
Early treatment is key to help slow further wasting and build strength. Options may include
physical therapy, nutritional counseling, hormone or supplement therapy, medications, assistive devices, and exercise. Preventing disuse and maintaining a protein-rich diet are also recommended.
In some cases, the specific cause cannot be identified. But there are still ways to manage symptoms and improve quality of life. Consider asking your doctor about specialized
